For some time testing the FES on a few cars: Bravo / Brava 1.2 16V 1999-2000 year.
I wanted to write a few things that do not work in my program. And read some of the values deviate from the actual value of the real thing.
The first thing concerns: battery charging and battery voltage.
In all four cars that diagnose FES program (any version) shows me the battery voltage: between 11.90V to 12.05 V = weak battery.
The service checked all 4 batteries, and he also checked and the voltage is correct: 12.70 V to 12.83 V = this is true - these batteries are new.
The second thing is charging when the engine is running.
Showing 13.74 to 13.80V with no load = in the Bravo / Brava is to say that the alternator is replaced.
If you add gas to the voltage drops in the FES!
2000rpm = 13.66V,
3000rpm = 13.56V ....... etc. and should grow?
If you add load: fan, heated rear window, light is measured decreases of up to 11.90V - 12.10V is already a drama
The service charge checked in all 4 cars and result it's = from 14.17V to 14.30 V at idle speed, no load on the engine. This is a correct indication.
differences in the program and in fact are too large and for the average user, and indicate a weak battery and the alternator is faulty. A few friends after the diagnosis (marea/brava too)was returned to me on this account. When they went to the car electrician to confirm this fact. As it turned out everything was ok also, it's just cheated program.
The third problem is the execution of test actuators.
can not perform the test water temperature control.
engine fan test also does not work.
ABS - sometimes you can not perform the test sensors: writes the inscription was not performed or disconnects after running the test
Another thing to scan airbag: a few times doing the scan driver airbag in the same car with different composition showed airbags: 2F, then, 2F-2L, and recently 2F-2L-2S. every time otherwise detect.
One last point I want to hook up my old topic that I established for the disconnection and latency too .Unless all interested parties have forgotten about it

This is what I gave above is not a super serious problem, but if we report any deficiencies and bugs that I did. Prior to testing, of course, a few times on several cars error to exclude one car error- engine,abs or airbag driver.
greetings to you all & do not be mad at me Yani that I wrote it here.
